Thanks for allowing me into the group. I recently bought a 2008 Cabriolet that had 116,000 miles on it. I’ve notice now that I’ve put about 5,000 miles on that the oil has to be topped up to full about every 1,000 miles give it take. It takes a full quart each time I top it up and is right at the full mark. Not a big deal if you’re not driving 120 highway miles. Unfortunately I am. Is this considered high consumption? I’ve check for leaks, blow by, and smoking and none of the symptoms are there. Not sure where the oil is going. Checked the antifreeze and it’s full and of the right color. I’ve looked into Lucas oil stabilizer to add after the next 1,000 mile top off. Should I try this to slow the consumption? I was using 5w30 Mobile 1 and changed it again once I noticed it was using oil. Went to the Mobil 1 Euro 0w40 and no change. Now I’m just topping off each time with 5w40. Thoughts on whether the Lucas will help this issue or should I step up to a thicker viscosity oil? Thanks.
